'TO ALL WHOM IT MAY CONCERN:

Be it known that I, N. EVINGER, of Terre Haute, in thecountyof Vigo, andState of Indiana, have invente'd a. new and useful Improvement inEvaporators and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable those skilled in theart tomake and use the same, reference being had to theaccom'panyingdrawings,'forming part of 'this specification, inwhich- 4 Figure 1 is atop or plan view of my improved evap'orator, part being broken away toshow the coustruction.

' Similar lett'bf reference indicate corresponding parts. i i

My nventionvhas for its 'object to furnish an improved apparatus forevaporating cane or other saccharine juice, for the/manu facture ofmolasses and sugar, and it consist'sin the construction, combination,and arrangement of the various p'arts as'hereinafter more fullydescribed. i

A is the furnace, which is made with three separate fire-chambers, a aand a The main fire-chan'ber, a has its grate in its forward end, andits 'ear partis divided by a'partitiou, as shown in fig. 1, se that theflame, smoke, and other products of combustion may pass back to the rearend of the said furnace-chamber a then turmand pass back to near themiddle of said chamber, where it passes out into the chimney B, beingall theitime directly beneath the boiler or pan C.

' The parts a and a of the furnace are placed, side by side, at the sideof the part a 'and the products of combustion pass from them directly.into the chamber a from which they escape, in the manner hereinbeforedescribed. i v

The lower part of the r'ear end 'ofthe chamber a is partially filled up,as shown in fig. 1, so as to contract the fiue and keep the hot productsof combuston close to the bottom of the pan or-boilerC. i

The pan or boiler C is made deep and large enough to cover and fit uponthe top of the part a of the furnace A, and is provided with astop-cock, D, through which the juice, at the proper time, can be drawnofl'into the -other'pans. i i' The inner mouth ot' the',discharging-opificc, in which the cock D is placed, is covered with asemi-tubular cover or cap, E, having an opening in its forward side,through which the juice passes to reach the dischargingorifice Thedischarging-orifice is also cover-ed w'ithasemi-conical strainer, F,nttached to asliding gate, G, said sliding gate having an opening in itslower end, corresponding in position with the said dischargigprifice.This enables the sti-einer to be removed, when desired, for cleaning orother purposes.

H and I are two shallow pans,' placed 'over the parts i"' andwt of thefurnace, and which are provided with `handles at their sides and oneend, as shown in figs. land 2.' I

J is a frame or rock, placed at the front of the partise and a forcouveniencej shifting and emptying the pans H and I.

'K is the hand-book, the-lower'end of which is -forkeh and has a" hookfo'rmed upon the end of each of its two branc'hes, so that the positionsof the pans H andI may be shifted upon the furnace readily and safely bytaking hold of one oi' the handles o'f said panswithithesaid hook.

Insiug the evaporator, the juice is allowed to flow in a. continuousstream from the cane-mill, or from a suitable reservoir, into the deepboileror pan 0, where it is slowly boiled, causing the scum to rise andthe guu and other sediment to settle. i

i When sufiicientl boiled, it' is drawn oif, throughthe cock D, in tothe panH.

When it is desired that the juice should g-anulate, the cappr coverE isused,` whichikeepsback the gum and other sedinent that would prevent orretrd granulation.

The juice, when in the pans H and I, is boiledmuch more rapidly,'as.there is now no dahger of it scorching or burning. V i v V When thejuice in the pan I is boiled down sufliciently, the said pan, by meansof the hand-hack K, is drawn from the' furnace upon the frane or reck J,where it is tlted, and the sirup or molasscs poured out.

The pan H is then drawn frou the part a of the furnace to the part a andthe pau I is placed upon the part a to receive another supply of j cefrom thepau or boiler C, in the manner hereinbefore described.

I claim' as new, and desire to secure by Letters Patent- '1. The furnaceA, constructed in three parts, a a a a'nd arranged. substantally asherein shown and described, and for the purpose setj'orth. i, I

. 2. The combinaton of the three pnns or boilers G, H, and I,constructed as described, with each other and with the parts a a a? ofthe furnace A, substantially as herein shownand described, and for thepurpose set forth.

3. The straining-device, constructed as described, of the sliding gateG, carrying the semi-conical streiner F, enclosed by the semi-tubularcover E, all arranged iu -relation with the faucet D and side of the panC, as

herein described, for the purpose specified.

4.' The combinatiou of the frame or rack J with the parts a? and *a ofthe furnace A, and with the pans H substantially as herein shown anddescribed, and for the purpose set forth. I

5. The hand-book K, constructed substantially as heroin shown anddescribed', when used in connecton with 'the pens H I, as and fer thepurpose set forth.
